The USRP N200 series provides high-bandwidth, high-dynamic range processing capability. The product architecture includes a Xilinx® Spartan® 3A-DSP 1800 FPGA, 100 MS/s dual ADC, 400 MS/s dual DAC and Gigabit Ethernet connectivity to stream data to host processors. A modular design allows the USRP N200 to operate from DC to 6 GHz. An expansion port allows multiple USRP N200 series devices to be synchronized and used in a MIMO configuration. An optional GPSDO module can also be used to discipline the USRP N200 reference clock to within 0.01 ppm of the worldwide GPS standard. The USRP N200 can stream up to 50 MS/s to and from host applications, and users can implement custom functions in the FPGA fabric, or in the on-board 32-bit RISC softcore. The FPGA offers the potential to process up to 100 MHz of RF bandwidth in both the transmit and receive directions. The FPGA firmware can be reloaded through the Gigabit Ethernet interface.
